The present invention is directed towards proposing cosmeticcompositions comprising alkylcellulose, which are intended in particularfor making up and/or caring for the lips or the skin, especially thelips, which are capable of producing a deposit, especially a makeupdeposit, which shows good cosmetic properties, especially in terms ofcomfort, absence of tack and gloss.

In general, cosmetic compositions need to afford an aesthetic effectwhen applied to the skin and/or the lips, and to maintain this aestheticeffect over time.

Specifically, the production of an aesthetic effect, after applying acosmetic composition, results from an assembly of properties intrinsicto the composition which are expressed in terms of makeup performance,cosmetic properties such as comfort on application (ease of application,glidance on application) and while wearing the composition (sparinglytacky or non-tacky), satisfactory homogeneity, lightness and gloss ofthe deposit produced with the composition.

In particular, the production of a solid composition, for example instick form, which is hard enough not to break during application whileat the same time being easily eroded on application, and which ishomogeneous and stable over time at room temperature and at 45° C., andwhose deposit on the skin or the lips is light and sufficiently glossy,is an ongoing preoccupation of formulators working in the field oflipsticks and other skincare and/or lipcare products (for instancebalms).

Ethylcellulose is already known in cosmetic and/or therapeuticcompositions, as a film-forming agent, for facilitating the formation ofa film on the skin and/or the lips, and for improving the waterresistance of this film.

Unfortunately, ethylcellulose, and alkylcelluloses in general (with analkyl group comprising from 1 to 6 carbon atoms), is of limitedsolubility in the majority of the solvents commonly used in cosmeticand/or dermatological formulations. In general, monoalcohols containingfrom 2 to 8 carbon atoms, such as ethanol, butanol, methanol orisopropanol, are preferred for dissolving sufficient amounts ofethylcellulose in cosmetic or pharmaceutical compositions. Evaporationof the C₂-C₈ monoalcohols leads, after application of the correspondingcosmetic composition to the skin or the lips, firstly to concentrationof the deposit and secondly to the formation of a coat on the surface ofthe skin or the lips that has a very good wear property. For example,document WO 96/36310 proposes cosmetic compositions especiallycomprising ethylcellulose dissolved in ethyl alcohol (SDA 38B-190 or SDA40B-190 solvents).

However, these volatile monoalcohols have the drawback of beingpotentially irritant to the skin and/or the lips, and consequently mayprove to be detrimental in the case of repeated use on the skin.

In order to overcome this problem, it has been proposed in document U.S.Pat. No. 5,908,631 to use, as an alternative to C₂-C₈ monoalcohols, acertain number of solvents for ethylcellulose, such as lanolin oil,certain triglycerides, certain propylene glycol or neopentyl glycolesters, isostearyl lactate, and mixtures thereof.

Unfortunately, replacing these C₂-C₈ monoalcohols, which are volatilecompounds, with these non-volatile solvents may on the other hand proveto be detrimental in terms of comfort and of tackiness of the resultingdeposit.

Consequently, there is still a need for cosmetic compositions, which arefree of C₂-C₈ monoalcohols, comprising a sufficient amount ofalkylcellulose, and which are capable of forming on the skin and/or thelips a deposit that has gloss and comfort properties and that is nottacky.

There is more particularly a need for compositions for making up and/orcaring for the skin and/or the lips, which are homogeneous and stableover time (especially for 72 hours at 24° C. and for 72 hours at 45°C.), in particular which do not undergo phase separation and which donot form grains, which are easy to apply and which allow the productionof a uniform, light, fresh, non-migrating deposit which, in particular,is sparingly tacky or non-tacky and satisfactorily glossy and which, incertain embodiments, has satisfactory wear properties.

One aim of the invention is to propose a composition whose texture ishomogeneous, and in particular which does not have any lumps and whichis stable at 24° C. and at 45° C.

The object of the present invention is, precisely, to satisfy theseneeds.

As emerges from the examples presented below, the inventors havediscovered that the abovementioned expectations can be satisfied byformulating the alkylcellulose in the form of a dispersion in water witha mixture of specific oils other than C₂-C₅ monoalcohols.

Thus, according to a first of its aspects, a subject of the presentinvention is a cosmetic composition comprising, in a physiologicallyacceptable medium:

at least water, preferably at least 5% by weight of water;

at least alkylcellulose, the alkyl residue of which comprises between 1and 6 carbon atoms, preferably between 2 and 6 carbon atoms andpreferably between 2 and 3 carbon atoms, preferably ethylcellulose,preferably at least 5% of ethylcellulose;

at least one first hydrocarbon-based non-volatile oil, chosen from:

-   -   C₁₀-C₂₆ alcohols, preferably monoalcohols;    -   optionally hydroxylated monoesters, diesters or triesters of a        C₂-C₈ monocarboxylic or polycarboxylic acid and of a C₂-C₈        alcohol;    -   esters of a C₂-C₈ polyol and of one or more C₂-C₈ carboxylic        acids,

at least one second non-volatile oil chosen from silicone oils and/orfluoro oils or hydrocarbon-based oils other than the said first oil;

at least one wax;

at least one hydrophilic gelling agent chosen from nonionic associativepolymers of polyurethane type, preferably polyoxyethylenated;

preferably at least one surfactant, preferably non-ionic.

Advantageously, a cosmetic composition according to the invention ishomogeneous, stable (no exudation or phase separation) over time(especially after 72 hours or even 1 month at 24° C. and at 45° C.),easy to apply to the skin and/or the lips, and produces a uniform, freshdeposit that is non-migrating and non-tacky or sparingly tacky, andsatisfactorily glossy.

Preferably, the composition is a composition for making up and/or caringfor the skin and/or the lips. According to a preferred embodiment, thecomposition is a lip product. More preferably, the composition accordingto the invention is in the form of a lipstick or a lip balm, preferablyin the form of a butter or a stick. The composition according to theinvention may also be cast in a jar or dish.

The composition according to the invention also concerns a process formaking up and/or caring for the skin and/or the lips, preferably thelips.

A composition according to the invention also proves to be particularlysuitable for the use of water-soluble dyes.

As emerges from the examples below, the combination of the oils underconsideration according to the invention proves to be particularlyadvantageous for formulating alkylcelluloses, preferably such asethylcellulose, in the said composition.

A composition according to the invention advantageously allows the useof an effective amount of alkylcellulose. For the purposes of thepresent invention, the term “effective amount” means an amount that issufficient to obtain the expected effect, as described previously.

In particular, a composition according to the invention comprises atleast 1% and particularly preferably at least 4% by weight (solids) ofalkylcellulose (preferentially ethylcellulose) relative to the totalweight of the composition.

Particularly preferably, the composition according to the inventioncomprises from 4% to 60% by weight of alkylcellulose (preferablyethylcellulose), more preferably from 5% to 30% by weight and morepreferably still from 5% to 20% by weight, relative to the total weightof the composition.

The term “physiologically acceptable medium” is intended to denote amedium that is particularly suitable for the application of acomposition according to the invention to the skin and/or the lips.

According to a first embodiment, the composition according to theinvention may be in the form of a butter (i.e. in the form of a thickcream or a paste). Its texture may be more or less thick. It may then,for example, be cast in a jar or in a dish.

Preferably, when the composition is in the form of a butter or a paste,it has a viscosity at 20° C. of greater than 1 Pa·s. Preferably, it hasa viscosity of between 1 and 25 Pa·s.

Protocol for Measuring the Viscosity:

According to this embodiment, when the composition according to theinvention is in the form of a paste at 20° C. (the term “paste” or“butter” means a composition that is therefore not solid, and whoseviscosity can be measured), its viscosity may be measured according tothe following protocol:

The viscosity measurement is carried out at 20° C., using a RheomatRM180 viscometer equipped with a No. 4 spindle, the measurement beingcarried out after rotating the spindle for 10 minutes (at the end ofwhich time stabilization of the viscosity and of the rotational speed ofthe spindle are observed), at a shear rate of 200 s⁻¹.

The composition according to the invention has at 20° C. a viscosity ofbetween 1 and 25 Pa·s and preferably between 1.5 and 18 Pa·s.

Preferably, the viscosity at 20° C. of a composition according to theinvention is between 2 and 16 Pa·s.

According to a second embodiment, the composition according to theinvention is in solid form, for example in the form of a stick. The term“solid” refers to a composition whose hardness, measured according tothe following protocol, is greater than or equal to 30 Nm⁻¹ at atemperature of 20° C. and at atmospheric pressure (760 mmHg).

Protocol for Measuring the Hardness:

The hardness of the composition is measured according to the followingprotocol:

The lipstick is stored at 20° C. for 24 hours before measuring thehardness.

The hardness may be measured at 20° C. via the “cheese wire” method,which consists in transversely cutting a wand of product, which ispreferably a circular cylinder, by means of a rigid tungsten wire 250 μmin diameter, by moving the wire relative to the stick at a speed of 100mm/minute.

The hardness of the samples of compositions of the invention, expressedin Nm⁻¹, is measured using a DFGS2 tensile testing machine from thecompany Indelco-Chatillon.

The measurement is repeated three times and then averaged. The averageof the three values read using the tensile testing machine mentionedabove, noted Y, is given in grams. This average is converted intonewtons and then divided by L which represents the longest distancethrough which the wire passes. In the case of a cylindrical wand, L isequal to the diameter (in metres).

The hardness is converted into Nm⁻¹ by the equation below:

(Y×10⁻³×9.8)/L

For a measurement at a different temperature, the stick is stored for 24hours at this new temperature before the measurement.

According to a second embodiment, the composition according to theinvention may be in the form of a stick. In particular, when thecomposition is in the form of a stick, for example in the case of astick of lipstick, it has a hardness that is sufficient for the sticknot to break when it is applied to the skin and/or the lips.

According to this measuring method, the composition according to theinvention preferably has a hardness at 20° C. and at atmosphericpressure greater than or equal to 35 Nm⁻¹.

Preferably, the composition according to the invention especially has ahardness at 20° C. of less than 300 Nm⁻¹, especially less than 200 Nm⁻¹and preferably less than 150 Nm⁻¹.

The compositions obtained preferentially have a hardness of between 30and 115 Nm⁻¹ and preferentially between 35 and 80 Nm⁻¹. Preferably, thecompositions according to the invention are in the form of a stick,preferably with a diameter of 12.7 mm.

In particular, when the composition is in the form of a stick, forexample in the case of a stick of lipstick, it has a hardness that issufficient for the stick not to break when it is applied to the skinand/or the lips.

A composition according to the invention is preferably in the form of anemulsion of oil in an aqueous phase, conventionally known as an“oil-in-water emulsion”.

Preferably, the cosmetic composition according to the invention is asolid lipstick, such as a stick of lipstick, a lip balm or a lipstickcast in a dish, for example. The term “balm” means a coloured oruncoloured, solid composition, which is generally intended for caringfor the lips, preferably by means of the presence of a hydrophilicactive agent.

According to one particular embodiment, a composition of the inventioncomprises less than 5% by weight of silicone surfactant(s), inparticular less than 4% by weight, especially less than 3% by weight,more particularly less than 2% by weight and in particular less than 1%by weight, or even is totally free of silicone surfactant.

According to another of its aspects, a subject of the present patentapplication is a cosmetic process for making up and/or caring for thelips and/or the skin, in particular the lips, comprising at least onestep that consists in applying to the lips and/or the skin at least onecomposition as defined previously.

Particularly preferably, the composition according to the inventioncomprises from 4% to 60% by weight of alkylcellulose (preferentially ofC2 to C6), more preferably from 5% to 30% by weight and more preferablystill from 5% to 20% by weight, relative to the total weight of the saidcomposition.

The alkylcellulose is a cellulose alkyl ether comprising a chain formedfrom β-anhydroglucose units linked together via acetal bonds. Eachanhydroglucose unit contains three replaceable hydroxyl groups, all orsome of these hydroxyl groups being able to react according to thefollowing reaction:

RONa+C₂H₅Cl→ROC₂H₅+NaCl, in which R represents a cellulose radical.

Advantageously, the alkylcellulose is chosen from methylcellulose,ethylcellulose and propylcellulose.

According to one particularly preferred embodiment, the alkylcelluloseis ethylcellulose.

It is a cellulose ethyl ether.

Total substitution of the three hydroxyl groups would lead for eachanhydroglucose unit to a degree of substitution of 3, in other words toa content of alkoxy groups of 54.88%.

The ethylcellulose polymers used in a cosmetic composition according tothe invention are preferentially polymers with a degree of substitutionwith ethoxy groups ranging from 2.5 to 2.6 per anhydroglucose unit, inother words comprising a content of ethoxy groups ranging from 44% to50%.

According to a preferred mode, the alkylcellulose (preferablyethylcellulose) is used in a composition of the invention in the form ofparticles dispersed in an aqueous phase, like a dispersion of latex orpseudolatex type. The techniques for preparing these latex dispersionsare well known to those skilled in the art.

The product sold by the company FMC Biopolymer under the name AquacoatECD-30, which consists of a dispersion of ethylcellulose at a rate ofabout 26.2% by weight in water and stabilized with sodium lauryl sulfateand cetyl alcohol, is most particularly suitable for use as an aqueousdispersion of ethylcellulose.

In particular, when the composition is in the form of a stick, forexample in the case of a stick of lipstick, it has a hardness that issufficient for the stick not to break when it is applied to the skinand/or the lips.

Additional Fatty Substance:

Besides the oils and the waxes described previously, the compositionunder consideration according to the invention may also comprise atleast one additional fatty substance, in particular at least one pastyfatty substance.

Pasty Fatty Substances

The composition under consideration according to the invention may alsocomprise at least one pasty fatty substance.

For the purposes of the present invention, the term “pasty fattysubstance” (also known as pasty fatty substance) means a lipophilicfatty compound with a reversible solid/liquid change of state,exhibiting an anisotropic crystalline organization in the solid state,and comprising, at a temperature of 23° C., a liquid fraction and asolid fraction.

In other words, the starting melting point of the pasty compound can beless than 23° C. The liquid fraction of the pasty compound, measured at23° C., can represent from 9% to 97% by weight of the compound. Thisliquid fraction at 23° C. preferably represents between 15% and 85% andmore preferably between 40% and 85% by weight.

Within the meaning of the invention, the melting point corresponds tothe temperature of the most endothermic peak observed in thermalanalysis (DSC) as described in Standard ISO 11357-3; 1999. The meltingpoint of a pasty substance or of a wax may be measured using adifferential scanning calorimeter (DSC), for example the calorimetersold under the name MDSC 2920 by the company TA Instruments.

The measuring protocol is as follows:

A sample of 5 mg of paste or wax (depending on the case) placed in acrucible is subjected to a first temperature rise passing from −20° C.to 100° C., at the heating rate of 10° C./minute, then is cooled from100° C. to −20° C. at a cooling rate of 10° C./minute and finallysubjected to a second temperature rise passing from −20° C. to 100° C.at a heating rate of 5° C./minute. During the second temperature rise,the variation in the difference in power absorbed by the empty crucibleand the crucible containing the sample of pasty substance or wax ismeasured as a function of the temperature. The melting point of thecompound is the value of the temperature corresponding to the tip of thepeak of the curve representing the variation in the difference in powerabsorbed as a function of the temperature.

The liquid fraction by weight of the pasty compound at 23° C. is equalto the ratio of the enthalpy of fusion consumed at 23° C. to theenthalpy of fusion of the pasty compound.

The enthalpy of fusion of the pasty compound is the enthalpy consumed bythe compound in order to change from the solid state to the liquidstate. The pasty compound is said to be in the solid state when all ofits mass is in crystalline solid form. The pasty compound is said to bein the liquid state when all of its mass is in liquid form.

The heat of fusion of the pasty compound is equal to the area under thecurve of the thermogram obtained using a differential scanningcalorimeter (DSC), such as the calorimeter sold under the name MDSC 2920by the company TA Instrument, with a temperature rise of 5° C. or 10° C.per minute, according to standard ISO 11357-3:1999. The enthalpy offusion of the pasty compound is the amount of energy necessary to makethe compound change from the solid state to the liquid state. It isexpressed in J/g.

The heat of fusion consumed at 23° C. is the amount of energy absorbedby the sample to change from the solid state to the state that it has at23° C., composed of a liquid fraction and a solid fraction.

The liquid fraction of the pasty compound measured at 32° C. preferablyrepresents from 30% to 100% by weight of the compound, preferably from50% to 100%, more preferably from 60% to 100% by weight of the compound.When the liquid fraction of the pasty compound measured at 32° C. isequal to 100%, the temperature of the end of the melting range of thepasty compound is less than or equal to 32° C.

The liquid fraction of the pasty compound measured at 32° C. is equal tothe ratio of the enthalpy of fusion consumed at 32° C. to the enthalpyof fusion of the pasty compound. The enthalpy of fusion consumed at 32°C. is calculated in the same way as the enthalpy of fusion consumed at23° C.

The composition according to the invention comprises at least onehydrophilic gelling agent chosen from non-ionic associative polymers ofpolyurethane type.

Preferably, the composition is such that the associative polymer ofpolyurethane type is present in a content ranging from 0.1% to 10% byweight, relative to the total weight of the composition.

For the purposes of the present patent application, the term “polymerfor gelling the aqueous phase” means a polymer that is capable ofgelling the aqueous phase of the compositions according to theinvention.

The gelling polymer that may be used according to the invention mayespecially be characterized by its capacity to form in water, beyond acertain concentration C*, a gel characterized by oscillatory rheology(μ=1 Hz) by a flow threshold τ_(c) at least equal to 10 Pa. Thisconcentration C* may vary widely according to the nature of the gellingpolymer under consideration.

By way of illustration, this concentration is between 1% and 2% byweight for an acrylamide/sodium acrylamido-2-methylpropanesulfonatecopolymer as an inverse emulsion at 40% in polysorbate 80/I-C16, forinstance the product sold under the name Simulgel 600 by the companySEPPIC, and is about 0.5% by weight for an AMPS/ethoxylated (25 EO)cetearyl methacrylate copolymer crosslinked with trimethylolpropanetriacrylate (TMPTA) of the type such as Aristoflex HMS.

The gelling polymer may be present in the composition in an amount thatis sufficient to adjust the stiffness modulus G* (1 Hz, 25° C.) of thecomposition to a value greater than or equal to 10 000 Pa and especiallyranging from 10 000 Pa to 100 000 Pa. The method for measuring thestiffness modulus G* (1 Hz, 25° C.) of the composition is described ingreater detail hereinbelow.

The gelling polymer is a hydrophilic polymer and is thus present in theaqueous phase of the composition.

For the purposes of the present invention, the term “associativepolymer” means any amphiphilic polymer comprising in its structure atleast one fatty chain and at least one hydrophilic portion. Theassociative polymers in accordance with the present invention may beanionic, cationic, nonionic or amphoteric.

Associative polyurethanes are nonionic block copolymers comprising inthe chain both hydrophilic blocks usually of polyoxyethylene nature(polyurethanes may also be referred to as polyurethane polyethers), andhydrophobic blocks that may be aliphatic sequences alone and/orcycloaliphatic and/or aromatic sequences.

In particular, these polymers comprise at least two hydrocarbon-basedlipophilic chains containing from 6 to 30 carbon atoms, separated by ahydrophilic block, the hydrocarbon-based chains possibly being pendentchains or chains at the end of the hydrophilic block. In particular, itis possible for one or more pendent chains to be envisaged. In addition,the polymer may comprise a hydrocarbon-based chain at one end or at bothends of a hydrophilic block.

Associative polyurethanes may be block polymers, in triblock ormultiblock form. The hydrophobic blocks may thus be at each end of thechain (for example: triblock copolymer containing a hydrophilic centralblock) or distributed both at the ends and in the chain (for example:multiblock copolymer). These polymers may also be graft polymers or starpolymers. Preferably, the associative polyurethanes are triblockcopolymers in which the hydrophilic block is a polyoxyethylene chaincomprising from 50 to 1000 oxyethylene groups. In general, associativepolyurethanes comprise a urethane bond between the hydrophilic blocks,whence arises the name.

Preparation Protocol:

-   -   1) The fatty phase (the wax) was heated to 75° C. in the phenyl        silicone oil in a heating pan. The mixture is then left to cool        to 70° C.    -   2) The surfactant was added and the mixture was stirred at        55° C. until homogeneous.    -   3) The ethylcellulose and the octyldodecanol were poured into a        beaker. The mixture was then stirred using a Rayneri-type        deflocculator for 1 hour at 55° C., followed by addition of the        water, the Rheolate FX1100, the dyes, the preserving agents and        the glycerol, and the mixture was stirred with the Rayneri        deflocculator at 55° C. until a homogeneous mixture was        obtained.    -   4) This mixture was then poured into the fatty phase and stirred        (Rayneri deflocculator) until a homogeneous mixture was        obtained.    -   5) It was finally cast into jars 3.3 cm in diameter. The jars        were then left to cool to room temperature.

After 24 hours at room temperature, the compositions obtained wereevaluated and their viscosity was measured according to the protocoldescribed previously.

The stability of the compositions was evaluated by placing thecompositions obtained for 72 hours at 24° C. and for 72 hours at 45° C.The compositions were especially checked to see if phase separation, theformation of grains or collapse was observed in the case of solidcompositions, or if a variation in viscosity was observed in the case ofcompositions in butter form.

Compositions 1 and 2 according to the invention produced a lipstick inthe form of a lip butter. The compositions obtained are homogeneous.

Each of the compositions was applied to the lips using an applicator offoam gloss type so as to form a deposit of uniform thickness; the easeof application and the appearance of the deposit were evaluated.Furthermore, the tacky nature of the deposit was evaluated during dryingof the formulation after 2 minutes at room temperature (25° C.). To dothis, a finger was applied, after the specified drying time, onto theapplied formula and the tack was assessed by the person on removal ofhis finger from the applied formulation.

For compositions 1 and 2 according to the invention, the application tothe lips is easy (glidant on application and soft composition). Thedeposits obtained are homogeneous, light and fresh. Furthermore, thedeposits obtained are sparingly tacky, do not migrate and aresatisfactorily glossy. With compositions 1 and 2, the deposit obtainedadditionally has a sensation of softness of the lips.
